Subject: Logarithmic transformation of not normal data
Hi,
I've made a multiple linear regression using SPSS by one dependent variable
and two indepent variables and all assumptions were satisfied but R squre
is very low about 0.3,so I think that is because my variable are not
normally distributed that's why I was thinking about transforming my data
uasing logarithmic transformation to normal distributio and repeat the
regression,but I don't know how to transform them?
and do I have to test any other assumptions after applying the
transformation?]
Thanks
